+# Adafruit Community Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and leaders pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level or type of
+experience, education, socio-economic status, nationality, personal appearance,
+race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+We are committed to providing a friendly, safe and welcoming environment for
+all.
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Be kind and courteous to others
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Collaborating with other community members
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and sexual attention or advances
+* The use of inappropriate images, including in a community member's avatar
+* The use of inappropriate language, including in a community member's nickname
+* Any spamming, flaming, baiting or other attention-stealing behavior
+* Excessive or unwelcome helping; answering outside the scope of the question
+  asked
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+  address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate
+
+The goal of the standards and moderation guidelines outlined here is to build
+and maintain a respectful community. We ask that you don’t just aim to be
+"technically unimpeachable", but rather try to be your best self. 
+
+We value many things beyond technical expertise, including collaboration and
+supporting others within our community. Providing a positive experience for
+other community members can have a much more significant impact than simply
+providing the correct answer.
+
+## Our Responsibilities
+
+Project leaders are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project leaders have the right and responsibility to remove, edit, or
+reject messages, comments, commits, code, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any community member for other behaviors that they deem
+inappropriate, threatening, offensive, or harmful.
+
+## Moderation
+
+Instances of behaviors that violate the Adafruit Community Code of Conduct
+may be reported by any member of the community. Community members are
+encouraged to report these situations, including situations they witness
+involving other community members.
+
+You may report in the following ways:
+
+In any situation, you may send an email to <support@adafruit.com>.
+
+On the Adafruit Discord, you may send an open message from any channel
+to all Community Helpers by tagging @community helpers. You may also send an
+open message from any channel, or a direct message to @kattni#1507,
+@tannewt#4653, @Dan Halbert#1614, @cater#2442, @sommersoft#0222, or
+@Andon#8175.
+
+Email and direct message reports will be kept confidential.
+
+In situations on Discord where the issue is particularly egregious, possibly
+illegal, requires immediate action, or violates the Discord terms of service,
+you should also report the message directly to Discord.
+
+These are the steps for upholding our community’s standards of conduct.
+
+1. Any member of the community may report any situation that violates the
+Adafruit Community Code of Conduct. All reports will be reviewed and
+investigated.
+2. If the behavior is an egregious violation, the community member who
+committed the violation may be banned immediately, without warning.
+3. Otherwise, moderators will first respond to such behavior with a warning.
+4. Moderators follow a soft "three strikes" policy - the community member may
+be given another chance, if they are receptive to the warning and change their
+behavior.
+5. If the community member is unreceptive or unreasonable when warned by a
+moderator, or the warning goes unheeded, they may be banned for a first or
+second offense. Repeated offenses will result in the community member being
+banned.
+
+## Scope
+
+This Code of Conduct and the enforcement policies listed above apply to all
+Adafruit Community venues. This includes but is not limited to any community
+spaces (both public and private), the entire Adafruit Discord server, and
+Adafruit GitHub repositories. Examples of Adafruit Community spaces include
+but are not limited to meet-ups, audio chats on the Adafruit Discord, or
+interaction at a conference.
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. As a community
+member, you are representing our community, and are expected to behave
+accordingly.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 1.4, available at
+<https://www.contributor-covenant.org/version/1/4/code-of-conduct.html>,
+and the [Rust Code of Conduct](https://www.rust-lang.org/en-US/conduct.html).
+
+For other projects adopting the Adafruit Community Code of
+Conduct, please contact the maintainers of those projects for enforcement.
+If you wish to use this code of conduct for your own project, consider
+explicitly mentioning your moderation policy or making a copy with your
+own moderation policy so as to avoid confusion.
